The popular Unity Revamped PPA has stopped working once again a while back, but there's a new PPA that adds the same features to Unity along with some extra ones such as the Unity Touch Launcher icons.

The new Unity Revamped PPA, maintained by Garhuy, is only available for Ubuntu 12.04 LTS and adds the following features to Unity (with Compiz):

re-added Dodge Windows behavior;

minimize on click for Launcher items;

option to enable/disable the Workspace Switcher icon on the Launcher

Ubuntu Raring launcher assets (the new BFB icon - the button used to open Dash, workspace switcher, etc);

Also, the PPA description mentions that you should also get an option to allow the menus to be permanently visible, however, in my test I couldn't find this option in CCSM so I think the patch for this has been removed.
